Keyword - Host cell outer membrane (KW-1033)

Keywords navigation



Protein found in or associated with the prokaryotic cell outer membrane, a selectively permeable membrane which separates the prokaryotic periplasm from its surroundings in prokaryotes with 2 membranes. Traditionally only Gram-negative bacteria were thought of as having an outer membrane, but recent work has shown some Actinobacteria, including Mycobacterium tuberculosis, as well as at least 1 archaea (Ignicoccus hospitalis) have a cell outer membrane.
